Objective Europa is a crowd researched project, that aims to send human beings to Jupiter’s moon Europa.It will be on a one way mission in search of extraterrestrial life while expanding the borders of exploration and knowledge for all mankind.The starting point of Objective Europa is purely theoretical, but will move into more advanced phases including prototyping, technology try-outs, and eventually a crewed launch.Our website (http://www.objective-europa.com/info/ ) isn't fully online yet, but we are working hard at it.

If you think this sounds interesting you can see more info on one of the links bellow:

In the near, or even medium term (20-50 yrs)? Yes, totally impossible barring the extraordinary (aliens setting up a used spaceship dealership on Earth, etc).

National governments and even international consortium can't summon the resources to get to the nearby Moon in less than the above time frame. A manned mission to Mars is still in the wishful thinking stages. We have no idea of how to really get people across deep space, much less way WAY out to the Jovian system.

Sorry dude, your aim is admirably high, but completely unrealistic. You can ponder the technical problems and solutions, but you might as well be writing science fiction.

Note that this project was founded by amongst others Kristian von Bengtson of Copenhagen Suborbitals. He already has a near-term achievable goal that they're successfully working towards. As I understand it, the main aim is to encourage people to get interested in space flight, and to get an idea of what would be needed for such a mission. I don't think they're really expecting to go, at least not in the way that they're expecting to launch a human into suborbital space with Copenhagen Suborbitals. I'd say that that is a worthy enough goal.

50 years is a long time frame. 50 years ago we'd only had manned orbital capability for a few years. Having a Martian colony and mature Lunar infrastructure within 30 years doesn't seem unrealistic, given the current levels of interest (i.e. billionaires who want to Make It So). That leaves us with 20 years to set up the mission and launch it, and if most of it is already planned...

If I had a billion dollars to spend, though, I'd spend it on Polywell fusion and a reusable TSTO system. In fact, that would probably leave me with half of the money left...

50 years is a long time... And maybe it takes longer before we can do it. But someone has to start thinking the "extreme" ideas...
